How This Calculator Works

Actual Load (kW) = kVA × Load% × Power Factor Fuel Consumption ≈ Actual kW × 0.27 L/kWh (Industry standard: 0.25–0.30 L/kWh for diesel)

Running a DG at 70–80% load gives best fuel efficiency. Below 50% load, fuel consumption per kWh increases significantly.

DG SizekW at 75% loadApprox. L/hr
25 kVA15 kW~4.2 L/hr
62.5 kVA37.5 kW~10.5 L/hr
125 kVA75 kW~21 L/hr
250 kVA150 kW~42 L/hr
500 kVA300 kW~84 L/hr

Actual consumption varies by DG brand, age and maintenance condition.
